Best Tower Fans with Air Purifier 2021 (Ionizer & HEPA Filter)

Clean air is very important for a healthy life. But due to increasing pollution around the globe, only a scarce number of cities can claim to have a clean environment. The cleanest of environments have been filled with visible and invisible particles, disfavouring our health and aggravating already existing health issues.

This particular issue has prompted Tower fan companies to use air purifying technology in their fans to remove air pollutants. Air purifying technology is helpful for people who suffer from asthma or allergies and it even gets rid of secondhand smoke in the house.

Did you know, this smoke contains more than 7000 chemicals and about 70 of them can cause cancer. Therefore, you need a tower fan with an air purifier to enjoy the benefits of breathing clean air.

HEPA filter and Ionizer is used in tower fans to blow purified air and keep the environment clean. HEPA filters use a web of woven fibres to trap pollution particles that are drawn into the filter.

On the other hand, Ionizer uses an electrostatic charge to remove pollutants, allergens and other unwanted particles from the atmosphere.

Best Tower Fans with Ionizers

I know you’ll never compromise on anything that affects your health. So we’ll review here some of the best Tower fans with ionizer to make it easy for you to choose the best Tower fans with Ionizer.

Let’s first see how an Ionizer works.

Ionizer air purifier doesn’t have a web of fibers to trap pollutants – as we had in an HEPA filter. It uses an electrostatic charge to remove pollutants and allergens from the atmosphere in your home/office.

An Ionizer air purifier releases negatively charged ions into the air which attract the positive ones, such as dust and allergens and bind together with them. In this way, it brings down the pollutants from air, as these over-weighted particles are no longer light enough to stay airborne.

In addition, some ionizers come with a special electrostatic collection plates whose job is to attract pollutants and trap them on its surface. This plate is reusable and must be washed regularly to maintain its effectiveness.

Best Tower Fans with HEPA filter

Dyson is the only brand that makes these filters, and it uses HEPA filters in its tower fans, instead of air ionizers. There are some major differences between how both types of air purifiers work to clean the air.

High-Efficiency Particulate Air filters – also known as HEPA filters – are widely popular for offering the highest standard of air purification in the current market. HEPA filters use a web of woven fibres to trap the airborne particles, drawn into the filter. They are capable of capturing both big and small size particles – thanks to their intelligently designed mechanism.

HEPA filters are capable of capturing at least 99.97% airborne particles which are 0.3 microns or larger. This makes them extremely effective, maximizing the quality of air in the room.

These filters have a very intricate mechanism, and Dyson is the only brand that makes these. HEPA filters need regular cleaning, and this cleaning process has to be carried out diligently. Moreover, after a certain amount of time, you’ll have to replace it with a new one.

Have you checked our reviews on some of the best Dyson Tower fans? If you are thinking of buying one of such fans that come with a HEPA filter, check out our reviews to learn about their mechanism, pros and cons before spending your hard-earned cash on them.

Difference Between Ionizer and HEPA filter

As said above both the technologies have their own ways of purifying the air.

The HEPA filter sucks the indoor air into the device and traps airborne contaminants. And then it releases the pure air back into the room. It can even trap cigarette smoke.

On the other hand, an ionizer sends electrically charged ions into the atmosphere that makes a bond with the pollutant – described above – and takes them down.

Some ionizers use a collection of plates to collect these. But there is a disadvantage of the mechanism that an ionizer follows. There are always chances of impurities contaminating the room again.

But if you talk about their area coverage, ionizer can cover an air space up to 1000 sq. ft, which is way more than the average area a HEPA filter can cover. HEPA filters come with different area coverage, but it is limited to around 450 sq. ft.

Buyer’s Guide for Tower Fans with Air Purifier

As we have discussed the numerous benefits of having a tower fan that not only blows air around the room, but also improves the quality of air. Before buying a tower fan with an air purifier, one should have essential knowledge about them to choose the right one.

There are two types of air purifying technologies being used in tower fans – HEPA filter and air ionizer. And both these technologies have their limits. In the buyer’s guide, we shall expound further on how to choose the right tower fan with an air purifier that meets your objectives.

HEPA filter is for Small Area

Although there is no fixed limit of how much area a HEPA filter can cover, as different types of filters have different limits. But as compared to air ionizer, HEPA filter is for smaller areas up to 450 sq.ft. This is where you have to make the decision whether you need a tower fan with HEPA filter or air ionizer.

Moreover, HEPA filter is a long-term solution as it can be helpful to completely eliminate the dust particles from the room.

Air Ionizer can cover Big Area

On the other hand, if you intend to use your tower fan in a bigger room or around 500-1000 sq. ft. hall, you need a tower fan with air ionizer. Air ionizer is known for its wider area coverage.

However, an air ionizer is never a permanent solution – as we have discussed above – the dust particles remain in the room, though not airborne. Air ionizers are also known to emit Ozone in small quantities, which can cause photochemical smog and even trigger respiratory discomfort.

So, it’s up to your preferences, whether you want to cover a bigger area or you simply want to completely remove the dust particles from your room. For a bigger area, you need a tower fan with an air ionizer. And for more effective purification in medium to big size rooms, a HEPA filter gets the job done.
